M4 SA-F21 FLEX ETU TAN RIFLE SPECNA ARMS (SPE-01-040805)

The replica has been very well fitted and the user will not feel any play between the lower and upper body. The use of a reinforced nylon body and front has allowed for a reduction in weight, making it ideal as a replica for dynamic CQB games. Additionally, the nylon fiber reinforcement makes the construction more durable than other polymer constructions.

The replica uses a quick-change spring system. This allows for quick and efficient adaptation of the replica's power to the conditions expected on the battlefield without the need for access to a workshop or a set of specialized tools.

The replica has a factory-built SA ETU 2 circuit, which results in the ability to set the following:
Serial firing mode: 1 to 5 shots in automatic mode
Binary Trigger
Trigger sensitivity (3 levels of settings)
Furthermore, the SA ETU 2 circuit protects the engine from current overloads and has the ability to alarm in case of too high or low battery voltage.
The circuit has a built-in activity control mode; after one hour of inactivity, the circuit will shut down and you will need to reconnect the battery to the replica to restart.

The F21 is equipped first of all with:
an inner barrel 229 mm long and 6.03 mm in diameter.
small weight of just over 2 kg
Extended magazine release
adjustable length breech
oblique fire mode switch
Practical and stylish 7-inch M-Lok handguard
Replica Suppressor (14mm CCW Thread)

Internally, the replica features a Gearbox V2 version, with an integrated quick-change spring system. The adjustment of the Hop-Up system is done via a rotary unit. Inside you will also find steel gears and 8mm diameter bearings.
